Man, I'm American and I still can't comprehend it. I need to actually visit one next time I'm further east.

This one is near Fort Collins, Colorado. Last stop before I hit Wyoming!
I saw them last time I was in Oklahoma, and I just never stopped in. Apparently there's another local phenomenon there called Brahms, which is kind of the same thing.
Dude, I went to that one 2 weeks ago!
Ye olde I-25 Buckees. Out of town family went there once, became addicted to some of their branded junk food, and now we replenish their supply when we visit.
